Recovering From Mistakes
Undo an action
▶
Choose the menu command Edit > Undo.
You can undo an unlimited number of actions!
Redo an action
▶
Choose the menu command Edit > Redo.
Not only can you undo your previous actions, you can also redo them. Redo—the opposite of
Undo—(believe it or not) undoes your undo. It puts your commands back into effect. You can
continue redoing all the commands in the undo list until it is empty. Nisus Writer Pro remembers
the Redo list as long as you do not make any editing changes to your text. You can Undo and Redo
any number of times, but as soon as you resume editing your document, Nisus Writer Pro clears the
Redo list. The Undo list continues to accumulate the new commands you make.
To help you visualize these Undo and Redo lists, imagine that the process of preparing your
document is like a walk across an open field with many branching paths. As illustrated in Figure
48, you can take any path you like. Having gone a certain distance along the green path ABCD in
the figure, you change your mind and want to go back to the point B (Undo Bold) which you passed.
That is what multiple undos allow you to do.
Figure 48
The Undo and Redo paths
Imagine now that you have undone everything from changing the margin to bolding your selection,
you find that you have gone back too far and want to retrace your original path to redo the Bold and
redo the Delete (to point C having redone part of the original path) and start on the new red path
CEF (by making changes to your document). Immediately, Nisus Writer Pro forgets the rest of the
original green path CD (including the margin change). Nisus Writer Pro clears the Redo list before
the path to E begins. The new undo list, however, can get you back along any portion of the path
ABCEF.
